I want to fetch a part of string from a string. E.g. I have a string say sampleStringUrl which holds "http://some.something.net/update/user". So, I want to get only "some.something.net" from sampleStringUrl.
Like that you want to get Host URL.
var urlString = "https://stackoverflow.com/questions/6162522/get-the-domain-part-of-an-url-string"
var url = URL(string: urlString)
var domain = url?.host
print(domain!) //stackoverflow.com

For example I have
[
["A",1]
["B",5]
["C",3]
]
How do i sort it so that it returns in Highest to lowest value B, C, A
You can do in following way:
a.sort {
return $0.last as! Int > $1.last as! Int
}
Don't forget to add additional checks while using this code, case where the last item is not an integer or there is an array not in the expected format. Otherwise, it will lead to a crash.

Look at this:
glueContext.getSinkWithFormat(connectionType = "s3",
options = JsonOptions(
Map("path" -> outputLgSingleDir,
"partitionKeys" -> List("org_name"))),
format = "parquet", transformationContext = "")
.writeDynamicFrame(lHistory)
What possible values for JsonOptions are?

How can I search for a duplicate in a given string using a scriptlet?
ScripletInput= a,b,c,a
Here the letter 'a' is repeating. If it is repeating more than once, then it should exit, else it can go ahead.
Please see Remove occurrences of duplicate words in a string
The code below will remove duplicates in a string.
<script type="text/javascript">
str=prompt("Enter String::","");
arr=new Array();
arr=str.split(",");
unique=new Array();
for(i=0;i<arr.length;i++)
{
if((i==arr.indexOf(arr[i]))||(arr.indexOf(arr[i])==arr.lastIndexOf(arr[i])))
unique.push(arr[i]);
}
unique.join(",");
alert(unique);
</script>

var nsarray:[NSMutableDictionary] = [["object":["uid":["age":"26","gender":"male"]]]]
print(nsarray[0]["object"])
That is how it looks. I want to get the value "uid", so when it prints it is just "uid". Currently it is printing:
"uid":["age":"26","gender":"male"]
I want to get the "uid" value. Meaning when it prints it is just "uid". "uid" is a placeholder for a unique ID so I won't know what the uid is.
It looks like "object" key contains another dictionary, which has exactly one element. To get the first key, call allKeys to get keys, convert them to Array, and pick the the initial element:
let d = nsarray[0]["object"] as! NSDictionary
print(Array(d.allKeys)[0])
